IMPROVEMENT IN BOXES.

Specification forming part of Letters Patent No. 121,156,4dated November 21, 1871.

` To all whom fit may concern:

- drawing- Figure l represents a perspective view of one of my boxes. Fig. 2 is a horizontal section of the same in the plane a' x, Fig. 1. Fig. 3 is a perspective view of one of my metallic corner pieces detached.

Similar letters indicate corresponding parts.

This invention consists in the arrangement of a metallic corner piece stamped out of sheet metal and provided with pointed tongues or spurs, in combination with the sides, ends, tops, and bottoms of a box of wood or pasteboard, said parts of the box being perforated at the proper places for the reception of the spurs of the corner pieces in such a manner that, by passing said spurs through the perforations of the parts intended to constitute the box and turning them over on the inside, said parts of the box are firmly united by a simple and expeditious operation, and without the use of paste Or any other means for connecting these parts.

In the drawing, A designates a box, the body of which is made of the side pieces a and end pieces b. These pieces are united by metallic corner pieces, c, which are stamped out of sheet metal, and which are provided with pointed tongues or spurs d, projecting from their edges, as shown in Fig. 3. The parts which are to constitute the box are perforated at the proper places with holes for the reception of the spurs d, and by passing these spurs through said holes and turning them over on the inside, as shown in Fig. 2, the parts of the box are firmly united. The operation of applying the corner pieces and of turning over the spurs is effected by a proper machine constructed for this purpose, and it can be conducted with great ease and expedition. It is obvious that the bottom of the box can be attached to the side and end pieces in the same manner in which said side and end pieces are united.

What I claim as new, and desire to secure by Letters Patent, is

The arrangement of the metallic corner pieces provided with spurs d, in combination With the several parts constituting a box, said parts bre-` ing perforated for the reception of the spursjdfi? substantially in the manner herein shown/and JOSEPH GOHN.
